Javascript slider examples

JavaScript is a scripting language for the web. Microsoft refers to their implementation of it as "JScript" but in terms of syntax it's pretty much the same. jQuery is JavaScript. It is a JavaScript library, so it operates on top of JavaScript. It cannot exist on its own, so you can't use one over the other. You can use just JavaScript or JavaScript and jQuery. In other words, jQuery is a software library, written in JavaScript, whose intention is to help JavaScript developers when writing code that is to be run in a web page. jQuery is designed to make many JavaScript development tasks much easier. Use jQuery when it will significantly reduce your development time, and you can afford the extra overhead of downloading the library. Personally my reasons of using jQuery/JavaSccript libraries are: Complex element selection Animation Event handling crossbrowser support easy element selection customizable plugins large support community very popular jQ

hreflang? what is it? where does it come from?

Hreflang tags are a technical solution for sites that have similar content in multiple languages. The owner of a multilingual site wants search engines to send people to the content in their own language. Say a user is Dutch and the page that ranks is English, but there’s also a Dutch version. You would want Google to show the Dutch page in the search results for that Dutch user. This is the kind of problem hreflang was designed to solve. And for the  Webmasters who serve several versions of their content in different languages or for users in different countries should use   hreflang annotations   to help Google show the right version in the search results for each user.

Creating a file-based SWAP on your Beagleboard

On the Beagleboard you should expect to require a swap file given the limitation of how little RAM is available (between 256 MB and 512 MB). Some system programs like apt-get will only run properly when some swap space is present (due to 256 MB not being enough RAM). Some images (such as those from Linaro.org) do not come with a swap partition or any swap space allocated. Under Linux, swap space can be either a dedicated partition or a swap file. Both can be mounted as swap which the OS can access. Creating a Swapfile The following commands will create a 512MB file, limit access only to root, format it as swap and then make it available to the OS: sudo mkdir -p /var/cache/swap/ sudo dd if=/dev/zero of=/var/cache/swap/swapfile bs=1M count=512 sudo chmod 0600 /var/cache/swap/swapfile sudo mkswap /var/cache/swap/swapfile sudo swapon /var/cache/swap/swapfile To tell the OS to load this swapfile on each start up, edit the /etc/fstab file to include the following addi
